Today was sat at home and heard a pop from the kitchen, went in there and had water gushing everywhere from a burst on the flexible hose thing that connects the water supply to the boiler via the filling loop.

Managed to turn off the water at the mains after a couple of minutes as Thames have just fitted a water meter so for some reason I now have two stopcocks, one above the meter and one below (should they have installed it this way?). The damage wasn't too bad but a fair bit leaked down to the flat below.

I bought a new flexi and fitted it myself, turned the water back on and everything seems ok but am now really paranoid that it might happen again and it would be a disaster if I hadn't been at home, I've never seen so much water from a 2 minute leak and if it happened when I'd been out no one might have gotten to it for hours.

Have been googling and came across something called a 'Flood Stop Isolating Valve' and wondered if anyone knew if something like this would stop any future leak if the flexi hose failed again? Also would it be something I could install myself or should I pay to have a plumber install it and how much would that cost?

The only reason that one went 'pop' is because one of the two valves was left on probably with mains pressure. They aren't built to hold high pressure for any amount of time, just literally while you are re-pressurising the system. Make sure both black levers are turned off and you will be absolutely fine.
